Littelfuse adds high-speed fuses with bladed mounting options

Littelfuse’s POWR-SPEED PSR series of semiconductor fuses now includes new bolted and DIN blade models in various sizes and amperages
By Gina Roos, editor-in-chief.
Littelfuse, Inc. has expanded its line of POWR-SPEED PSR series of high-speed fuses with the introduction of 275 new bolted and DIN mounting options in various sizes and amperages. The PSR series fuses are used in power conversion and power conditioning equipment to provide over-current protection for critical power semiconductor devices such as diodes, triacs, IGBTs, SCRs, and MOSFETs.
These devices are designed to reduce the amount of short-circuit current to extend the life of power semiconductors. Saving space in power systems, the square-body design accommodates up to 2,000 amperage with up to 70 percent DC interrupting rating in a smaller footprint.
Key features include:
A selection of mounting terminations, including bladed and flush-mount options
A unique silicon sealant that prevents filler leakage to increase fuse reliability and keep equipment safe 
Up to 20 percent more DC voltage in a standard package size compared to existing products
Up to 70 percent more DC interrupting rating compared to existing products
Third-party DC certification printed on the product label, along with published DC information with global certifications, which help streamline UL inspections

Applications include power conversion device protection (UPS, inverters, rectifiers, drives), battery protection and energy storage systems, high-power DC systems (DC common bus, DC injection braking), and power supplies. They also can be used in electric vehicle charging stations, and heaters and welding equipment.
